1. In the Gram Stain procedure, which component acts as the mordant?

Correct answer: C

Rationale: In the Gram Stain procedure, the mordant is Gram's Iodine. The purpose of the mordant is to form a complex with the crystal violet, enhancing its ability to bind to the cell wall. Crystal violet is actually the primary stain used in the Gram Stain procedure to initially color all cells. Methyl alcohol is the decolorizer that removes the crystal violet from certain cell types. Safranin is the counterstain used to stain those cells that did not retain the crystal violet stain after the decolorization step.

2. When performing a physical examination, safety must be considered to protect the examiner and the patient against the spread of infection. Which of these statements describes the most appropriate action the nurse would take when performing a physical examination?

Correct answer: B

Rationale: The most appropriate action for the nurse to take when performing a physical examination is to wash their hands before and after every physical patient encounter. This practice helps prevent the spread of infection. Hands should also be washed after contact with blood, body fluids, secretions, and excretions, and after contact with any equipment contaminated with body fluids. It is crucial to wash hands after removing gloves, even if the gloves appear intact. Choice A is incorrect because washing hands after removing gloves is necessary to ensure thorough hygiene. Choice C is incorrect because hands should be washed before and after every patient encounter, not just before examining each body system. Choice D is incorrect because gloves should be worn when there is potential contact with body fluids, but they do not need to be worn throughout the entire examination.

3. What term is used to refer to generalized wasting of body tissues and malnutrition?

Correct answer: D

Rationale: Cachexia is the correct term used to describe the generalized wasting of body tissues, ill health, and malnutrition associated with some chronic diseases. It involves a loss of fat tissue to protect the bones and joints. Clients with cachexia are at risk of pressure ulcers and other complications due to malnutrition and poor health. Entropion refers to an eyelid condition, confabulation is a memory disturbance, and induration is the abnormal hardening of a part of the body.

4. The client often sighs and says in a monotone voice, 'I'm never going to get over this.' When encouraged to participate in care, the client says, 'I don't have the energy.' These cues are suggestive of which nursing diagnoses? Select all that apply.

Correct answer: A

Rationale: A nursing diagnosis involves clinical judgment about a response to a health problem. In this scenario, the client's expressions of feeling overwhelmed and lacking energy indicate feelings of hopelessness and powerlessness. While fatigue is mentioned, there is no direct evidence to support an interrupted sleep pattern, making option C incorrect. Similarly, disturbed self-esteem and self-care deficit are not evident from the given cues, making options D and E incorrect.

5. What is the primary purpose of a patient care meeting or conference?

Correct answer: B

Rationale: The primary purpose of a patient care meeting or conference is to determine how the healthcare team can best meet the patient's needs. These meetings involve discussions among healthcare professionals to tailor the care plan to the specific needs and preferences of the patient. Option A is incorrect because financial discussions are generally not the primary focus of patient care meetings. Option C is incorrect as the patient's physical status is usually already known and is not the primary purpose of the meeting. Option D is incorrect as psychosocial aspects, while important, are not the sole focus of the meeting, which is primarily about addressing the patient's overall needs and preferences.
